esbuild Bundler for Monosize

This package provides an `esbuild`-based bundler plugin for the `monosize` package size measurement tool. It enables `monosize` to use `esbuild` for creating optimized bundles, allowing developers to accurately assess the size implications of their code using a high-performance bundler. The current stable version is 0.3.2, and its release cadence is typically tied to updates in `monosize` or `esbuild` itself. Key differentiators include its seamless integration into the `monosize.config.mjs` setup, support for `esbuild`'s full configuration options via a callback, and optimized batch build modes for faster measurements compared to sequential builds. It leverages `esbuild`'s speed and efficiency to provide quick and reliable size reports.
